How do I resolve a string that has unicode characters written in that way: \u003C, \u0022

Question

I have string which contains substrings like \u0022, \u003C, \n and want to replace them by the characters they stand for. What's the most straight forward way? Of course I could do something like

code = code.replaceAll("\\\\u003C", "<");

for each such character, but that's a little bit annoying.

Edit: To make it clear, I have already a string like

code="Hello \\u0022 World \\n \\u003C And so on.";

@darshakat I have to admit, you have the fastest hand on the wild west — ginkul, Feb 26 '20 at 07:03
I have read those threads before I posted this here. But the strings there are different from mine. I actually have `\u0022` as substring (this are six characters). In the examples `\u0022` is only one character. — principal-ideal-domain, Feb 26 '20 at 08:17
The dupe goes over your exact situation, see [this answer](https://stackoverflow.com/a/14368185/485343) for example. — rustyx, Feb 26 '20 at 12:16
@rustyx Could you please reopen my question? My question is different from the linked one. — principal-ideal-domain, Feb 26 '20 at 12:49

public static void main(String[] args) throws FileNotFoundException, IOException {
    Properties properties = new Properties();
    String str = "unicodedString=Hello \\u0022 World \\n \\u003C And so on.";
    StringReader stringReader = new StringReader(str);
    properties.load(stringReader);
    System.out.println(properties.getProperty("unicodedString"));
}

output

Hello " World 
 < And so on.

Your string is the wrong string to start with. Use double backslash to get a string of my kind. – principal-ideal-domain Feb 26 '20 at 08:15
@principal-ideal-domain I have updated my answer , let me know if it works for u. – Amit Kumar Lal Feb 26 '20 at 11:19
In your answer you're reading the String from a file. In my case I have it already stored in a string. How would I do it then? – principal-ideal-domain Feb 26 '20 at 12:07
@principal-ideal-domain check updated answer – Amit Kumar Lal Feb 26 '20 at 13:38
